PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition in which Ag, Au, etc., can be used as inner conductive substances and not containing PbO and Bi2O3. SOLUTION: This dielectric porcelain composition is represented by the general formula: xBaO.yNd2O3.zTiO2 [6<=(x)<=23, 13<=(y)<=30, 64<=(z)<=68, (x)+(y)+(z)=100], and contains a Cu oxide in an amount of 0.1-3.0 wt.% (converted into CuO) and a glass composition in an amount of 2.0-10 wt.% as auxiliary components. >=90 wt.% of the glass composition is selected from SiO2, B2o3, MgO, BaO, SrO, ZnO and CaO. 5 wt.%<=SiO2<=15 wt.%, 15 wt.%<=B2O3<=25 wt.%, 50 wt.%<=(MgO+BaO+SrO+ZnO+CaO)<=80 wt.%, and 90 wt.%<=(SiO2+B2O3+MgO+BaO+SrO+ZnO+CaO)<=100 wt.%. |
